Welcome to the PF.

The Relevant Equation that you list is not applicable. Look for an equation that relates the period of oscillation of a spring+mass system to the spring constant K and the mass m. (or else just derive the equation yourself from what you know about how springs and masses work...) :-)

Now that I look at it closely. The answer has got to be C because each oscillation is the same as the previous.

I don't think so. Adding mass will slow down the oscillations...

I see so the answer has got to be E since we know its the same cylinder it would reduce the time by twice.

No. You need the equation which relates period and mass.
